i'o @ZZ whom it may concern: g

l Be it known that We, EDWARD G. FLAGER and FRED L. MGGAHAN, citizens of the United States, residing at the city of St. Louis, in the State of Missouri, have invented acertainnew and useful Fluid-Fuel Burner, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and 1o use the same, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to burners for fluid fuels, such as crude petroleum, and has for its 1 5 object to provide a burner whichmay be used in lamps and for other similar purposes and which by a properly-directed supply of the fuela'nd air will bring about perfect combustion. f zo In the drawings, in which like characters of reference refer to similar parts in the different views, Figure 1 is a vertical section of the burner and casing. Fig. 2 shows in section the burner applied to a lamp. Fig. 3 is a top 25 plan view of the base of the burner. Fig. 4 is a detail view of a part of the burner, and Fig. 5 is a vertical section of the base and the superposed portion forming the oil-chamber.

In the drawings, is an o en-ended casi 3o ing forming an air-flue throug the middle of the base 11 of the lamp. This base 1 1 is provided with a chimney 12, mounted thereupon and held in position by a spring-clamp 13. A

perforated mantle 14 is mountedupon the top 3 5 of the base and surrounds the upper end of the casing 10. The burner itself, which 1s mounted inthe upper end of the caslng 10, may be said to consist of three portions.

15 represents the base portion of the 4o burner, which is circular in form and 1s supported by means of brackets 16, attached to the sides of the casing 10. The relative d1- ameters of the base 15 of the burner and the interior of the casing 10 are such that an alrpassage 17 is left between them. The periphery of the base 1 5 rovlded w1th an upwardly-projecting fl e 18. Ooncentrically .g formed on the upper side of the base 15 is a hollow truncated cone 19. l Through the top 5o of this cone 19 passes the pi e 20, by means of which oil is supplied to the urner under'pressure from the tank 21.v The base 15 1s also provided with an outer set of tubes 22 and an inner set of tubes 23, forming air-passages through said base; The tubes 23 are inclined inwardly `through the center of `the base. Both sets of tubes extend toa point a short distance above the flange18. Between the flange 18 and the cone 19 is formed the catchbasin 25.

26 represents the middle ortion of the burner, which is provided wit a socket and adapted to surround the truncated cone 19 to form the oil-chamber 27. The inner surface of this middle portion 26 is provided with a number of grooves 28, which serve to conduct the oil-supply from said chamber tothe catchbasin 25. A shoulder 30 is formed on the outer surface of the middle portion 26. Upon with flaring sides and has in its upper surface a depression 32, surrounding a raised central portion 33, in which the socket 34, which receives the upper portion of the middle portion, is formed.

35 is an air-deflector in the form of a ring having a beveled inner surface which serves to direct centrally the air passing upward through the air-passage 17. This air-deector 35 also serves as a valve to completely close the air-passage 17 when it is desired to do so. It is provided with lugs 36, projecting `outward through slots 37 in the casing 10.

38 represents thumb screws passing through and bearing against the eyes 39, carried by the outer side of the casing 10. The upper ends of these thumb-screws are screwthreaded and engage with screw-threaded openings in the lugs 36. By means of these thumbescrews the position of the air-deflector (315 in the casing 10 maybe regulated as desire The catch-basin 25 is lled, as shown in Fig. 5, with a body of refractory porous ma terial, such as asbestos fiber, fire-clay, mica, quartz, or other granulated or powdered substances.

In the operation of our invention oil is supburner and burned, the ainforsupp'orting 'combustion being supplied by means of the air-passage 17 and the tubular air-passages 22 and 23.

Having fully described our invention, what `we claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination with a fluid-receptacle, of a projection carried thereby, a cap surrounding said projection, means for feeding fluid fuel between said projection and cap, an outwardly-projecting deflector carriedby said cap, a set of vertical pipes passing through said receptacle, and a set of inwardly-inclined pipes passing through said receptacle.

2. The combination with a fuel-receptacle, of a projection carried thereby, a cap surrounding said projection, means for feeding fluid fuel between said projection and cap, an outwardly-projecting deflector carried by said cap, a filling of porous refractory material in said fuel-receptacle, a set of vertical pipes passin through said receptacle, and a set of inwar ly-inclined pipes passing through said receptacle. 1

3. The combination with a fuel-receptacle, of a projection extending upwardly therefrom, a cap surroundin said projection, means for feeding fiuid fue between said projection and cap, an outwardly-extending deflector carried b said cap, air-pipes extending through sai receptacle and terminating adjacent to said deflector, and an inwardlyprojecting defiector surrounding said fuel-receptacle.

4. The combination with a fuel-receptacle, of a projection extending upwardly therefrom, a cap surroundin said. projection, means for feeding fluid fue between said proj ection and cap, an outwardly-extending deflector carried by said cap, an inwardly-projecting deflector surrounding said fuel-receptacle, and means for adjusting the distance between said fuel-receptacle and said latter defiector.

5. The combination with an air-flue, of a fuel-receptacle arranged in said flue to leave an air-passage between said parts, a projection in said receptacle, a cap surroundin said projection, means'for feeding fluid fue betweensaid cap and projection,'adeflector carried by said cap, a second deflector car-` ried by said air-flue and extending over said carried by said cap, a second deflector carried in said air-fine and extending over said fuel-receptacle, and means for adjusting said latter deflector to control the flow of air between said iiue and fuel-receptacle.

7. The combination with an air-flue, of a fuel-receptacle arranged in said flue to leave a passage between said parts, a projection in said receptacle, a cap surrounding said projection, means for feeding fluid fuel between said projection and cap, an outwardly-extending deflector carried by said cap, a ring in said air-flue above said fuel-receptacle and forming an air-deflector therefor, and means situated outside of said flue for adjusting said rin The combination with an air-fine, of a fuel-receptacle arranged therein to leave an air-passage 'between said parts, a projection in said receptacle, a cap surrounding said projection, means for feeding fluid fuel between said projection and cap, an outwardly-extending deflector removably carried by said cap, a filling of porous refractory material in said receptacle, a set of vertical air-pipesl passing through said receptacle, a set of inwardly-inclined pipes passing through said receptacle, an air-defiector arranged in said flue above said fuel-receptacle, and means for adjustin said air-defiector.

In testimony wereof We have hereunto set our hands and afxed our seals in the presence of the subscribing witnesses,
